Interactive map to find out how a tsunami will affect your city

The first tsunami recorded in history is about 4,000 years old off the coast of Syria. Since then we have become accustomed to this type of natural phenomenon, which, according to studies, has a 100% probability of occurring in the Mediterranean in the coming years. With this in mind, the National Oceanic and Atmospheric Administration (NOAA) has used historical records and Google Maps technologies to create an interactive tsunami map.

There are several geological and historical records of tsunamis. The most threatened areas are located near major volcanoes or in seismically active areas. Tectonically induced tsunamis occur in Europe, mainly in the Mediterranean and Black Seas.. Tsunamis caused ​​by submarine or terrestrial landslides have occurred mainly in Norway, but alsoandn in some other areas of Europe. In general, it can be concluded that tsunamis are possible along all coasts that are located in tectonically active zones or in areas where submarine or landslides are possible. Although no devastating tsunamis have occurred in Europe in the last 100 years, the hazard potential remains high.

The greatest danger occurs in the eastern Mediterranean due to earthquakes along the Hellenic Arc, but most of the Mediterranean coast is prone to tsunami impact. “Our method,” explains Mathilde Sorensen from the University of Bergen, Norway, “allows us to identify the main sources of tsunami danger at any given location and to investigate the possibility of issuing timely tsunami warnings. We found that the probability of a tsunami wave exceeding 1 m somewhere in the Mediterranean Sea is 1.5 m higher than that of a tsunami wave in the Mediterranean Sea, and that the probability of a tsunami wave exceeding 1 m somewhere in the Mediterranean Sea is 1.5 m higher than that of a tsunami wave in the Mediterranean Sea. Mediterranean in the next 30 years is close to 100%. This underlines the urgent need for a tsunami warning system in the region.”

One of the great dangers of tsunamis is that, unlike wind waves that affect only the surface of the ocean, Tsunamis propagate (move) throughout the entire depth of the oceanfrom the surface to the bottom. Large tsunamis can even span entire oceans.

The speed depends on the depth of the water through which it travels. The deeper the water, the faster they move. For example, in the depths of the ocean, tsunamis They can move at more than 800 km/hFortunately, when it reaches shallow waters, it slows down. On the coast, most tsunamis slow down to approximately 30 to 50 km/h.

When a tsunami hits the coast, areas less than 8 meters above sea level and within a radius of 1.5 km are the ones that will be most at risk. Tsunamis that could occur on the Mediterranean coasts of Spain, with waves of 1 meterthey would not reach more than 1 km into solid ground.

When using the map, its authors warn that This is just an app based on estimates useful for information and in no way constitutes a guide, as it will depend on many factors that have not been taken into account.
